$BTC A hidden chip was found under a Ledger screen — and it changes how you should think about hardware wallet safety. Ledger confirmed an unauthorized hardware implant in a device connected to the CryptoBilis wallet-drain investigation, with estimated potential losses near $93M across 311 wallets on five chains. Former Mt. Gox CEO Mark Karpelès found a concealed module behind the screen of a Ledger Nano X bought through a Malaysian reseller. It reportedly contained a microcontroller, LTE hardware, an antenna, and an eSIM — potentially capable of capturing a recovery phrase during setup and transmitting it over cellular. Ledger says its own systems and services show no sign of compromise. The concern is the reseller and supply-chain channel, not a confirmed breach of Ledger’s backend. How to know your wallet is clean: Buy only from Ledger’s official store or a verified authorized retailer Inspect the packaging, screen, seams, and ports for signs of tampering Run Ledger’s official genuine-check, but do not treat it as absolute proof — it cannot rule out every physical modification Verify every receive address and transaction on the device screen itself Never enter your recovery phrase into a website, app, form, or support chat If you suspect tampering, stop using the device immediately and move funds to a newly generated wallet A genuine-looking box is not security. A clean supply chain is security. Your seed phrase is the master key to everything you own. If anyone asks for it, they are not support — they are the attack. #Ledger #CryptoSecurity #SelfCustody #HardwareWallet #Bitcoin
